Both phones are displaying out of range please advise


Walkie talkies talk to each other. Try transmitting (talk to each other) so they receive a signal first. Do it in the same room. The try for range. It is not much. Even for a GMRS radio, these are low power and short range. Under 2 miles, must be able to "see" each other.

Problem no squelch noise or speaker like its muted, but can hear weather ok shows receiving and ant ok


Since the radio cannot transmit on Weather bands, there is no need for the radio to detect if it is transmitting when receiving weather.
In CB mode (on CB channels) the radio will mute when transmitting. So... a guess is that it is muting, or transmitting all the time in CB mode. Check for a mic problem by removing the Mic from the radio ... if it receives CB with no mic connected, then there is an issue with the mic. Otherwise, unless the unit is in PA mode (public address mode) it is likely something internal and beyond the scope of this service.

My Midland walkie talkie quits transmitting about 3 seconds after I start transmitting


It is more likely a power issue. PTT switches do not normally cause a short circuit. Check the batteries, swap the batteries and see if that helps. Radios take a great deal more power to transmit than turn on or receive. If not the battery, try a low voltage battery, such as a cordless phone battery. If it still occurs, check your warrany and send it back to the factory.

When I plug in headphones the radio goes into transmit mode.


This is a common problem when the audio device is plugged in when the radio is turned on. Be certain to have your radio turned off when plugging in the audio device.

If this is not the case, your audio device is not compatible with your radio, or your radio has a bad accessory jack.

Best regards.

G-Shock Atomic Solar watch - ERR in atomic time keeping


The watch will set itself at specific time set times, this is likely to be at 0200 0400 and 0600.
You will however be required to set the time zone, the switch is likely to be on the back.
INFO:
Atomic Time Synchronisation:
How does it work.
SHORT VERSION:
Radio set clocks and watches receive a 60-kilohertz, radio signal from the NIST the official timekeeper for the US and is located in Boulder, Colorado. Ft. Collins. they use atomic clocks and transmits this official time via high frequency short-wave and low frequency AM radio signals, satellite transmission, Internet, and via telephone.

Vhf radio


If there is power output, you need to use a watt meter and verify that your antenna is good. Depending on the antenna you can also check for a shorted or open connector or cable with an ohm meter.

Hope that helps...

Long range mode


Hi,

For the Cobra PR4700WX:
The user's manual is available here
To turn on/off the long range mode - (If you are referring to low & high power); Press and hold the Hi•Low/Enter button for two seconds.
Alternately, if you are referring to the Light/Max Range (receive sensitivity), 3 options:
1. To briefly turn off auto squelch - Press the Light/Max Range button for less than five seconds. If you hear two beeps, you have turned the maximum range extender on.
2. To turn maximum range extender on - Press and hold the Light/Max Range button for at least five seconds until you hear
two beeps which indicates the maximum range extender is on.
3. To turn maximum range extender off - Press and release the Light/Max Range button or change channels.
Probable reason that "fishing was all right but for hunting there is to much static" is becasue these radios operate on line of sight principle. Anything that obstructs the linear view would reduce signal strength/range. There is not that much obstruction when fishing compared to that when hunting in the woods or rough uneven terrain.
Please note that when using Channels 1 through 7 and 15 through 22 on high power, the Hi icon will be visible on the display. When using those channels on low power and on Channels 8 through 14, the Low icon will be visible on the display.

For the Cobra PR3500DX:
The user's manual is available here.
The transmission message icon off when not in use - this icon will only display if the radio is receiving something or if your are pressing the PTT button.
The other three the transmission signal is on at all times - indicates that either you are transmitting (unlikely) or the radio is in constant receive mode (most likely). I would venture a guess that the Auto Squelch is switched "OFF" or Maximum Range is switched "ON"

Both the 4700 & 3500 has Power Saver and it is a built-in feature. Your radios have this unique circuit designed that extend battery life. If there are no transmissions for 10 seconds, the radio will automatically switch to Battery Save mode and the Power Saver icon will flash in the display. This will not affect the radio’s ability to receive incoming transmissions.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
